| Planet | Orbital period | Distance from star | Radius (Earths) | Mass (Earths) | Found | Method |
|---|---|---|---|---|---|---|
| HU Aqr AB b (disputed) | 6.543 years | 3.6 AU | at least 1,875 | 2011 | Eclipse Timing Variations | |
| HU Aqr AB c (disputed) | 11.96 years | 5.4 AU | at least 1,430 | 2011 | Eclipse Timing Variations |
"At least" is a minimum mass. Radial velocity can only measure mass times the sine of the orbit's tilt.
Star
- 5,952 K surface temperature
- 0.88 times the mass of the Sun
